On the picture you will see amongst some mushrooms, a black\blue blob. It has a central opening. I had been told that it may be a sea squirt.... but I beleive they dont move!

Over a period of around 2 weeks, this has moved up the rock about an inch.... any thoughts?

thanks

I need a close-up

The only thing I can think of is the "Black Limpet Slug"
Scutus sp. but it should have more than an inch in 2 weeks but who knows. A Squirt would have two openings and no they don't move.

best I can do at the moment...

maffu, is it attached to the rock? It appears to have an attachment point extending at the bottom of it?

I don't think that it is a sea squirt, but I just wanted to add that some are capable of movement. I have an orange and white colony that moves around quite a bit.

Yes, some of the colonials can move, but if this was a ascidian, it would be a sessile ascidian and they are attached.

Nicky, the attachment point is there.... but... as it has moved it seems to have withdrawn then attached.

I have not seen it physically move, but merely witnessed it in different shapes, and through photo comparison to real time, see that it has moved!

Since yesterday the attachment point has become more apparent .. and it has moved a further half a centimeter up the rock!

I am sure its not an unwelcome critter but would love to know what they (there is another one) are!!!

Thanks for the ongoing interest and support folks!
